摘要

A method for producing a specific enantiomer in a larger amount than the other enantiomer, said method comprising reacting a reaction substrate in the presence of cellulose nanofiber or a derivative thereof and a catalyst so as to improve the yield. The present invention makes it possible to improve the yield and enantioselectivity in an asymmetric synthesis reaction.
